Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71744, here are decompositions:

3 + 71741 = 71744
31 + 71713 = 71744
37 + 71707 = 71744
73 + 71671 = 71744
97 + 71647 = 71744
151 + 71593 = 71744
181 + 71563 = 71744
193 + 71551 = 71744

Showing the first eight; more decompositions exist.
